Physics Week in Review: November 8, 2014

It was a big week for physics in the movies, with the premiere of Interstellar, and the Stephen Hawking biopic The Theory of Everything. That translates into lots of pixels commenting on the science behind the films...

The Surreal Task of Landing on a Comet

On November 12th 2014 the European Space Agency’s Rosetta mission will eject the small robotic lander Philae on a trajectory that should take it down to the surface of comet 67P/Churyumov-Gerasimenko (or 67P/C-P for short)...

Failure to Launch Is Always An Option

Do not try this at home. A Russian Proton-M launch goes wrong – and it can happen to anyone (wait for the shock wave). A rocket is a controlled bomb.

Complex Life Owes Its Existence To Parasites?

Is complex life rare in the cosmos? The idea that it could be rests on the observation that the existence of life like us – with large, energy hungry, complicated cells – may be contingent on a number of very specific and unlikely factors in the history of the Earth...

Interstellar Environments May Breed Complex Organic Molecules

If biologically important organic molecules like amino acids could form in interstellar space, the implications would be enormous. On the Earth we find plenty of amino acid species inside certain types of meteorites, so at a minimum these compounds can form during the assembly of a proto-stellar, proto-planetary system (at least this one) and end [...]..
